Aren't spiders more individualistic than insects? That would fit with the idea of them being builders.

How's this?...

The Memnorak focus entirely on their work and typically ignore others around them. While a single Memnorak ship is extremely dangerous in war, they have trouble with group tactics and can often be outflanked. However they more than make up for this in the robustness of their ship construction. Their love of construction and their ability to concentrate on their work makes Memnorak ships some of the most rugged in the galaxy. It's said: "It's hard to find a Memnorak without his toolbox". Some races romanticise the Memnorak and the how they tend to fight with individual ships against whole fleets. Despite the odds in combat, their individual nature and tough ships consistently come out on top.
